Oprah interview on Dateline Sunday

Oprah Winfrey sat down for a rare, one on one interview with Dateline's Ann Curry where she shares intimate details of her life.

She talks about her fame, fortune, spirituality, and how "The Color Purple" has transformed her life.

"When I read the first line of Alice Walker's book 'The Color Purple,' I remember being - sitting home, and I think it took my breath away because, 'Oh my God, this, this is my story. This is my story. Somebody knows how I felt.' And at the time I read 'The Color Purple,' I had not told anybody that I had been sexually abused. So it was like Celie and Alice Walker knew. Oh, I'm a mess, Ann, stop this...Celie knew and Alice Walker Knew!"

The full interview will air on Dateline Sunday at seven o'clock.
